Nice compact crossover

Small and very functional crossover. Smooth frequency adjustment and pretty precise as far as I can tell by ear. Great value. I am using in a little bit of an unconventional set up in our boathouse and it fit the bill!

Great product. Love it.

Why are there two outputs for the mono? Do you still hook up to your subwoofer with a single sub cable on either of the two mono outputs?

On the Rolls SX45 - 2-Way Stereo Crossover. One is for the crossover for the speaker highs to lows. The other is a separate mono out to a sub.
